Ken: sounds like we’re working on the same stuff :-) ...I’ll respond to your questions to the developer mailing list.

Kieran: as I mentioned on the developer mailing list, I’m aware of the core patch you refer to, and my approach is complementary to it. However, you may want to reread my blog post, since contrary to your claim, my approach specifically doesn’t invoke PHP nor Drupal when serving out a cached page to an anonymous visitor. That’s the whole point, and why I’m not so interested in the core patch you speak about. As for Siege’s results, as I mention in the article, I was indeed getting error pages until I tuned my MySQL settings to be able to handle the Siege attack; therefore, the results presented here do not include failed requests.
